MATRIX R9 280X is built with carefully-designed massive 20-phase power delivery, unmatched by any other graphics card for the ultimate in performance & spectacular power delivery. This ensures ample room for experimental performance tuning, as its DIGI+ VRM digital voltage regulation design augments precision overclocking capabilities, which are further supported by the use of hardened Super Alloy Power capacitors, chokes, & MOSFETs. These components are forged under extreme pressure & temperatures to increase reliability, power output, & overall card lifespan while eliminating bothersome choke buzzing noise, unlike much tamer reference cards. All these & more enable the absolute best in overclocking potential & experience. ASUS thermal design utilizes all-copper heatpipes so heat is removed efficiently. It generates greater airflow yet performs quieter than reference in idle & full load thanks to dual sound-dampening fans.
